Steam Damper Air System Connections
The ADS-78 is manufactured with a pneumatic (piston) damper system, which requires an external supply
of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the
rear inner top area of the dryer just in front of the electric service relay box.
a. Air Requirements
b. Air Connection
Air connection to system --- 1/8” N.P.T.
c. Air Regulation
No air regulation or filtration is provided with the dryer. External regulation and filtration of 80 PSI (5.51
bar) must be provided. It is suggested that a regulator/filter gauge arrangement be added to the
compressed air line just before the dryer connection. This is necessary to ensure that correct and clean
air pressure is achieved.
